A young boy called 'Thomas' was seen screaming as a man apparently tried to drag him into a Cheltenham park.
Now police are trying to track down the boy to see if a crime has been committed.
The incident happened in Bishops Cleeve yesterday.
Police received a report at 6.10pm that around 30 minutes previously witnesses had seen a man holding onto a boy’s arm at the park on Two Hedges Road.
The child was screaming and as the man let go the boy ran away.
The man was described as black, around 5ft 9” tall and of slim build. He was wearing a grey top with two white stripes on it, black tracksuit bottoms, brown boots, sunglasses and a baseball cap.
It’s thought that the boy might be called Thomas and aged around 7 or 8 years old.
Inspector Owen Hughes said: “We don’t yet know the circumstances surrounding this incident and whether or not the boy and man are known to each other but we are taking it very seriously and need to speak to both of them, as well as anyone else that was in the park at the time.
“We’ve been carrying out enquiries with the local schools to try and identify the boy and following the report officers searched the area but neither the man nor the boy were found.
“As always we would also encourage parents to discuss the importance of the stranger danger message with their children.”
Anyone with any information about the incident is asked to contact Gloucestershire Police on 101, quoting incident number 335 of September 28.
